My forecast is still showing low 30s in Dallas with it reaching 35° on Sunday
Did this thing speed up? I need 33° to stick around through Sunday at least!

Shortwave is a-hole.

If that ridge was built up into eastern Alaska like it had been shown, it would evict all the cold from Canada and probably get all the way down south. Just in time to spin up a coastal low near the Gulf Coast.

Models starting to hold it up a little, and some split some of the arctic cold toward the NE. Even if it all stays together, the later cold is having a surface low too far south for Louisiana snow and instead ice storm the shittiest parts of SEC country and snow for the Ohio Valley.

No harm in watching the models a little longer though.

I’d say a high in the 20s is more than a frost but to each their own.

What you posted is the next system around mid-week the week after Valentine’s Day. Not the system for Valentine’s Day weekend.

The temp map is for Valentine’s Day, though.

Get that kind of cold near the gulf long enough, you'll spin up a low near the coast. Jet stream has dipped so you get some favorable upper dynamics and the big temperature difference with the gulf.

I do think this is going to produce an ice storm somewhere in the SE, just a matter of how far the cold gets south and when exactly the low pressure forms.

Saturday evening update:


Ice and snow are MOSTLY gone from the models now and the GFS still shows bitter cold temps while the EURO thinks the cold stays further north. Below are some highlights.




Friday - (GFS) 46 degrees at noon
(Canadian) 40 at noon

Saturday - (GFS) 36 degrees at noon
(Canadian) 49 at noon

Sunday - (GFS) 27 degrees at noon
(Canadian) 54 at noon

Monday - (GFS) 37 degrees at noon
(Canadian) 37 at noon

Tuesday - (GFS) 34 degrees at noon
(Canadian) 27 at 6:00am
(GFS) 36 at 6:00am

Wednesday - (GFS) 35 degrees at noon

Thursday - (GFS) 37 degrees at noon

Friday - (GFS) a sticky 48 degrees at noon

Precipitation is mostly out of the BR area this whole time but it’s definitely close enough to the region that the chance is there for some sleet/freezing rain issues much of the time.

Canadian model only goes to Tuesday morning at this time so no further info temperature wise there. The Canadian does give us a good bit of ice on early Tuesday morning.

Talking as though this is going to be nothing is being a little premature right now BUT it is worth noting that anytime the models start pushing back a significant event it usually ends up being wrong. Just my personal observation from years of watching weather models.

GFS is running now - so far Friday at noon is colder than the previous run, at 42 degrees.

33 at noon on Saturday.

Trending colder

These “weather experts” just guess their arse off a week before. Two days ago it said Watson would be down to 19F on Friday Feb 19. (Which now shows 39F). Huge f’n difference. Now it shows 34 as the coldest night the entire week. Idiots.
